The "module" function defined in R initialization script hangs forever when loading a module that does not exist

[fplazaonate]

To Reproduce

Steps to reproduce the behavior:

1. Open an R interpreter (version 4.4.1)
2. Run the following commands

source('/usr/share/modules/init/r.R')
module('load toto')

I am able to reproduce this issue on my side.

It looks like there is a wrong interaction with the output pager. I will investigate.

In the mean time, you may disable the pager prior running R:

$ module config pager cat

[xdelaruelle]

Issue occurs when stderr content is sent through the configured pager. This issue was not there on R 4.4.3. So a change introduced on R between versions 4.4.3 and 4.4.1 makes this issue appear.

Anyway, it seems more caution not to use pager when running modulecmd.tcl for script language. So I will disable pager when modulecmd.tcl is run for python, perl, ruby, tcl, cmake, r and lisp.
